PHILADELPHIA (AP) — Internet activists took an aerial jab at Comcast to celebrate new government rules affecting the Philadelphia-based corporation.

A plane towed a banner past company headquarters that said, “Comcast: Don’t Mess With the Internet.” It featured a picture of Grumpy Cat and the hashtags #SorryNotSorry and #NetNeutrality.

The Federal Communications Commission voted Thursday to impose strict regulations on Internet service providers like Comcast and Verizon. The rules aim to enforce “net neutrality,” the concept that companies shouldn’t block or slow web traffic, or create paid fast lanes.

The net neutrality groups Fight for the Future, Demand Progress and Free Press supported the decision. They hired the plane Friday.

Comcast says the FCC shouldn’t oversee the Internet using regulations designed for the 1930s phone system. A spokesperson didn’t comment on the stunt.
